AT TO RNEY United States Patent Otfice 3,426,809 Patented Feb. 11, 19693,426,809 LOOM BOX FRONT Furman S. Cox, Seneca, S.C., assignor toDeering Milliken Research Corporation, a corporation of Delaware FiledNov. 14, 1966, Ser. No. 593,906 US. Cl. 139-183 1 Claim Int. Cl. D03d49/54, 49/02 ABSTRACT OF THE DISCLOSURE A loom box front which has ahardened steel tip at the position where the shuttle enters the boxfront.

This invention relates generally to an improved loom and in particularto new and improved box fronts for loom shuttle boxes.

Prior to this invention right and left hand shuttle boxes on the loomhave been damaged by engaging with the shuttle as it passes back andforth across the loom. If the shuttle is the least bit out of alignmentit tended to strike the left and right hand box fronts, head on, causingdamage to the box front as well as damage to the shuttle. Further, theleather which was attached to the inside of the shuttle boxes was beinggouged and torn by the impact of the point of the shuttle resulting inconsiderable down time of the loom for repair and replacement of theleather lining for the shuttle boxes.

It is therefore an object of the invention to provide apparatus toreduce damage to the loom box front,

Another object of the invention is to provide apparatus to positivelyguide the shuttle as it enters the shuttle box so that it does not gougethe lining of the shuttle box.

It is a still further object of the invention to provide a new andimproved box front for the loom which is not readily damaged by theshuttle.

Other objects and advantages of my invention will become apparent as thespecification proceeds to describe the invention with reference to theaccompanying drawings, in which:

FIGURE 1 is a top partially schematic view of a loom and FIGURE 2 is ablown-up perspective view of the left hand box front shown in FIGURE 1.

Looking now to the drawings and in particular to FIG- URE 1, thereference numeral represents a conventional loom equipped with theherein disclosed invention. In a conventional manner warp yarn 12 from awarp beam 14 is passed through the harnesses 16 and the reed 18 where itis woven into fabric by the passage of the shuttle 20 back and forthacross the loom from left shuttle box 22 to the right shuttle box 24 andvice versa to interweave the warp yarns in controlled fashion. Referencenumeral 26 schematically represents the picker sticks which supply thepropelling force to the shuttle 20. From the reed 18 the woven fabric istaken up in conventional manner by the take-up roll 28.

The shuttle boxes 22 and 24 which hold the shuttle 20 between tripsacross the lay 30 are similar in function but different in constructiondue to the design of the loom. The box rears 32 of each of the boxes 22and 24 have a leather strip not shown which is operably associated withthe inner surface thereof to cooperate with the leather strips 34 and 36mounted on the box fronts 38 and 40-, respectively, to absorb the shockof the shuttle as it moves into the box and to rapidly deaccelerate thespeed of the shuttle. Prior to this invention when the path of travel ofthe shuttle 20 varied a small amount due to misalignment it tended tostrike the strips 34 and 36 gouging out a portion thereof necessitatingstopping of the loom to replace the strips. This resulted in anunnecessary expenditure for new strips, lost production time of the loomand expense of labor to repair the box fronts.

Looking now to FIGURES 1 and 2 and especially FIGURE 2 the new improvedleft hand box front 38 is shown. Prior to this improvement the leatherstrip 34 extended all around the nose portion 42 of the box front whichwas very susceptible to damage by the shuttle 20. To alleviate thissituation a hardened steel contoured member 44 is welded or otherwisesecured to the nose portion 42 of the box front 38 to provide a surfacewhich will not only stand up under the impact of the shuttle but iselliptically rounded to guide the shuttle 20 into the shuttle box inproper position.

The herein described improved box front for the loom shuttle boxesprovides many advantages over prior art devices. The improved box frontshave substantially reduced the necessity to stock a large supply ofleather strips for replacement. Further, the increased service life ofthe leather strips provide a substantial cost saving since it is not nownecessary to constantly replace damaged straps. Overshadowing thesesavings is a very substantial savings due to reduction in loom down timeand reduction of the labor necessary to repair the loom.

While the apparatus disclosed and described herein constitutes preferredforms of the invention, it will be understood that the apparatus iscapable of alteration not departing from the spirit of the invention andthat all modifications of the apparatus that fall within the scope ofthe appended claim are intended to be included herein.

That which is claimed is:

1. A box front for a loom comprising: an elongated metallic member, astrip of leather attached to one side of said member and extendingtoward one end of said member and a hardened steel shock resistantmember connected to said one end of said elongated metallic member,sai-d hardened steel member extending from said one end and contactingsaid strip of leather and having an outer surface contiguous with theouter surface of said leather strip.
